Plots of precipitation and 850-hPa winds

o The precipitation data comes from the real-time version of NASA’s TRMM multisatellite precipitation analysis (TMPA, TRMM product 3B42RT).

o Forecast data and 850-hPa wind analyses come from NCEP’s GFS model.

o Anomalies are calculated by subtracting the first four harmonics of the annual cycle. The annual cycle for precipitation is calculated from the research version of the NASA TRMM 3B42 (1998–2008), and the cycle for 850-hPa winds are calculated from ERA-interim reanalyses (1989–2008).

o All plots are made using NCAR Command Language (NCL).

o This website is supported by funding from the National Science Foundation.

NOTE: I have a new monitoring site: http://monitor.cicsnc.org/mjo/
but I will continue maintaining this website for the foreseeable future.

Regional rainfall maps

Maps of 850-hPa winds and rainfall rates
TMPA rainfall rates and 1° GFS analyses are used for the last 7 days
